  • THIS PROBLEM WILL BE FIXED ON Virtual Design VERSION V5R13
    GA level.
    Additional Closure Information:
    THIS PROBLEM WILL BE FIXED ON CATIA VERSION 5 RELEASE 13 GA
    level.
    Incident Diagnosis
    Two bad elements are generated because of the
    domain topology invalid for the mesh size value
    ( the domain is not closed!!)
    The twist is grenerated by the optimization.
    Correction Explanation
    Invalid quality check on the 1D node
    Answer and By-Pass
    Valid quality check, no twisted elements anymore.
    But the 2 elements REMAIN BAD because there
    has been a wrong user specification.

Temporary fix
